JERSEY CENTRAL POWER AND LIGHT COMPANY (0YSTER CREEK) - COMPLIANCE REPORT NO. 50-219/72-01 The enclosed. report of a special inspection of the subject facility on February 7,1972, is forwarded for information. The purpose of~
this inspection was to review the details relating to the January.28,
-1972 fish kill incident at Oyster Creek. No items of' noncompliance with Regulatory requirements were identified during the inspection.
Based on~the investigations conducted by the licensee and by the State of New' Jersey, it appears that the reactor shutdown contributed significantly to the localized fish kills (negative thermal pollution).
We understand that this and other environmental matters will'be considered further by'DRL'and DREP in the review of the full term license application, submitted by Jersey Central on March 6, 1972.
Preliminary information concerning this incident was contained in my February 16, 1972 memorandum to you forwarding CO Inquiry Report No. 50-219/72-03, and my March 10, 1972 note to A. Giambusso. We plan no further action.with regard to this matter; however, if you desire additional information, please let us know.

his increase in release rate near the and of the fuel cycle was expected considering the known condition of the fuel in the reactor.
A refueling outage is scheduled for April 21, 1972. Mr. McCluskey stated that the increase noted on March 15, 1972 was unusual and may have indicated an additional failure.
In reply to questions about Jersey Central's plans, Mr. McCluskey would not consnit Jersey Central to any action to minimize release rates other than to remain below Technical Specification limits.
We plan to contact tha Mealth and Safety Laboratory to see what their schedule is for retrieving radiation data from the vicinity of Oyster Creek. We will keep you informed of their findings and any new developments as is appropriate. The matter of stack release rates has been and will continue to be followed closely during our inspection program at this facility.

Description of Particular Event or Circtanstance:
Several hours after pulling control rods to maintain reactivity on March 15, 1972, the stack release rate suddenly increased from about 85,000 uci/second to an indicated 100,000 uCi/second. By 9:00 an l
on March 16, 1972, the release rate had decreased to approximately 90,000 uCi/second.
W The steady state release rate has been creeping up gradually since late February. Following the removal of contrci rods to compensate for fuel burn up, a marked increase in stack release rate occurs.
j Several hours later, the release rate decreases to an equilibrium value higher than the release rate prior to pulling control rods.-
The stack release rate on February 23,1972 was 55,400 uCi/second.
On March 11, the release rate was 75,000 uCi/second.
(Records of stack release rates following the return to power from a 50% power reduction on January 23, 1972 showed a release rate of 142,800 uCi/sec-and for about one hour with a gradual decrease. Reference CO Report 219/72-02.)
i C.
Action by Licensee:
Mr. McCluskey stated that the release rate would be maintained below the Technical Specification limit and agreed to notify
)
i Cxpliance (Newark) by telephone if the steady state release rate increases above 100,000 uCi/second.

By telephone call from Mr. T. McCluskey, Station Superintendent, on March 2, 1972.
B.
Description of Particular Event or Circumstance:
During a routine surveillance test on March 1,1972, one of the four scram dump volume 1e:<ml switches failed to respond to a simulated high level signal. The cause of the failure was determined to be an improper tilt of the switch arm assembly.
The mercury could not make proper contact to initiate a high level signal.
(An abnormally high level in this tank could cause an Q
increase in the control rod scram time.) This condition was i
corrected.
C.
Action by Licensee:
Replacement switches were ordered and will be installed when l
received.
The failure will be investigated by the Plant Operations Review Committee.
The licensee will submit a written report on this occurrence to DRL within 30 days.

FISHKILL FRCH SUDDEN DROP IN COOLING WATER TDiPERATURE i
q.
The subject inquiry report is forwarded for action. The effects of the 25'F delta temperature across the condenser appears to be a contributing factor to the fishkill.= Checks of comparable plants show that the condenser delta temperatures range from 150 to 320F.
Consideration to restricting the condenser delta temperatures at all power reactors may be appropriate.
Our inspector reviewed records of plant releases and inlet and outlet
- circulating temperature charts. The data appears to show a "cause and effect" relationship between cooling water tanperature and the-4,y dead fish. The temperature recorder on the condenser indicated that the inist cooling water tanparature dropped drastically during the i
1 two days prior to the shutdown. Mr. McCluskey stated that at this i
time, the inlet water temperature was near the threshold where the warm water fish can not survive. Paul Hamer, Marine Biologist for the State of New Jersey, was reported in the Trenton Sunday Times Advertiser to have stated that 99.97. of the dead fish were menhaden.
In that article, he estimated there were 200,000 dead fish. To
- our knowledge, this is tne highest fishkill estimate.
i Discussion with New Jersey State officials revealed that a labora-j tory analysis of samples of dead fish is in progress. They have l-agreed to supply the results of this analysis to Region I Compliance.
A licensee report to DRL on this natter is anticipated; even though it is not s cpecific Regulatory requirement.

Description of Particular 1-: vent or Ciretnr. stance:
A feature article in the Asbury Park Funday press on Je mary 30, t
1972 discussed a " big fish kill found near nuclear plant" (Oyster
.g Creek). Accompanyinp pictures showed dead fish in coves off harnegat p.ay between the discharp,e canal and t1.c inict canal.
f.iriilar articles appeared in otber daily area newspapers.
During the following veck, the cause of the fish hill van attributed to the sudden cooline of the water in the discharre canal when Oyster Creek van shut down for maintenance vori.
plant records show that a power reduction started at 10: 30 pn on January 27, 1972 and the plant was taken off line at approxi-nately 4:30 am on January 28, 1972. The reverator was put back on line at 4:2f1 an on January 31, la72. 'rerperature charts at the plant nhov that the condenser inlet tenterature 6 bich is t

. during most of the outage period with a total flow of approxi-mately 600,000 ppa. This flow, which mixes in the discharge canal with a creek named Oyster Creek, caut,ed the discharge canal temperature to drop rapidly at the point the discharge canal 1
leaven Jersey Central property. During the plant shutdown, the recorded tenperature at this point in the canni was in the range of 32 to 40 F. (Spikes an high as 600F were seen 0
on the tenperature chart; however, they appeared to be a nalfunc~
tion of the recorder.)
Records show that liquid radioactive vaste was discharged on both January 28 and 29; however, the records show that the releases were analyzed and were within established limits. Plant records show that no cheuical releases from the plant for calendar years 1971 and 1972. Itowever,10,000 gallons of chromated water were transferred to a tank truck for disposal by Sunco, Inc. of Caldwell, New Jersey in calendar year 1971.
C.
Action by Licensee:
A seeting van held with local officials from Ocean and Lacey Township on Fe1.ruary 1,1072 to discuss the cause of the " fish kill".
Accordinn to minutes of the meeting, the local officials were natisfied with Jersey Central's explanation of what happened Ew?
and that Jersey Central was doing all that was possible to pro-tect the environment. Jersey Central 1as retained a consulting biologist, Dr. Charles tbrtz, to aid in their investigation.
According to l*r. itcCluskey, Dr. L'urtz discussed the probica vith
- 'r T. G. Farvel19 Chief Ef ologist,1:nvironmental Protection j
Agency, during. a tour of the area where the dead finh were found.
ifr. Farvelis did not contact the plant directly. The " fish j
kill" was investigated for the ' tate of !!ew Jersey by Paul :laneter, Marine Biologint, and Bruce Young, Conservation Officer, of the Fish and Wildlife Service from the nearby Nacote Creek Fishery.
